Managed Networks

Managed networks are named lists of network segments serviced by a specific Safeguard for Privileged Passwords (SPP) or Safeguard for Privileged Sessions (SPS) appliance in a clustered environment. Managed networks are used for scheduling tasks, such as password or SSH key change, account discovery, sessions recording, and asset discovery to distribute the task load. Using managed networks, you can:

  • Distribute the load so there is minimal cluster traffic.
  • Specify to use the appliances that are closest to the target asset to perform the actual task.

An SPP cluster has a default managed network that consists of all cluster members. Other managed networks can be defined.

CAUTION: If the role of a managed host that belongs to a linked SPS cluster is changed or if a managed host is added or removed from the cluster, SPP will detect the change by querying each Central Management node and attempt to stay in sync with the SPS cluster topology. If the Central Management node is down, SPP warns the administrator there may be invalid policies with a message like: The session connection policy was not found, in addition to flagging each broken Access Request Policy with an Invalid notation (Administrative Tools | Entitlements | Access Request Policies tab). Based on the size of your network and other factors, this will take one to 10 minutes and, during this time window, an unavailable managed host may continue to appear on the Managed Networks page. Any requests made will be invalid and will not be able to be launch sessions.

Task delegation

A Safeguard for Privileged Passwords' cluster delegates platform management tasks (such as password and SSH key check and password and SSH key change) to appliances based on platform task load. The primary appliance performs delegation and evaluates cluster member suitability using an internal fitness score that is calculated by dividing the number of in-use platform task threads by the maximum number of allowed platform task threads.

The maximum number of allowed platform task threads can be adjusted using the Appliance/Settings API and adjusting the MaxPlatformTaskThreads value. By adjusting this number, you can tune task distribution.

IMPORTANT: Adjusting the MaxPlatformTaskThreads will impact SPP's available resources for handling access requests and may impact user experience. Best practice is to engage Professional Services if the value may need to be changed.

Increasing the maximum number of allowed platform task threads will decrease the fitness score thus increasing the number of tasks passed to that appliance.

The fitness score is cached and is recalculated in 8-minute intervals when the scheduler is not busy. When the scheduler is running tasks, the fitness score is calculated more frequently so the scheduler can dynamically adjust.

The selection of a Safeguard for Privileged Sessions (SPS) Appliance is primarily dependent on managed network rules. However, if there aren't any managed network rules or if the managed network rules result in more than one SPS appliances selected, a fitness score is used as the tie breaker. The fitness score is calculated based on the percentage of disk available minus the overall load average of the SPS appliance. (Load average is a Linux metric which provides a numerical indication of the overall resource capacity in use on the server.) The higher the fitness score, the more likely that the corresponding appliance will be selected.

Precedence

The selection made on the Entitlement | Access Request Policy tab takes precedence over the selections on ( desktop client) Settings | Cluster | Managed Networks/( web client) Appliance Management | Cluster | Managed Networks page. If a Managed Networks rule includes nodes from different SPS clusters, SPP will only select the nodes from the same cluster that was assigned on the Session Settings page of the Access Request Policy tab.

IMPORTANT: Discovery, password and SSH key check and change will not work if a managed network has been configured with a subnet but is not assigned to an appliance (the appliance is blank). If the managed network does not have an assigned appliance, a message like the following displays: No appliances in network '<NameOfEmptyNetwork>' available to execute platform task request. To resolve the issue, assign at least one appliance to manage the passwords, SSH key, and/or sessions or delete the managed network entry.

Go to Managed Networks:

  • web client: Navigate to Cluster | Managed Networks.
  • desktop client: Navigate to Administrative Tools | Settings | Cluster | Managed Networks.

The Managed Networks page displays the following information about previously defined managed networks. Initially, this page contains the properties for the Default Managed Network, which implicitly includes all networks and is served by all appliances in the cluster.

Table 199: Managed Networks: Properties
Property Description

Name

The name assigned to the managed network when it was added to Safeguard for Privileged Passwords.

Adding a managed network

Use the Managed Networks page on the Cluster settings view to add managed networks, which can be used to distribute the task load in a clustered environment. It is the responsibility of the Appliance Administrator to define and maintain managed networks.

To add a managed network

  1. Go to Managed Networks:
    • web client: Navigate to Cluster | Managed Networks.
    • desktop client: Navigate to Administrative Tools | Settings | Cluster | Managed Networks.
  2. Click Add.
  3. In the Managed Network dialog, provide the following information:

    1. Name: Enter the display name for the managed network. This may be the name of the Safeguard for Privileged Sessions Appliance used to authenticate the linked SPS session connection.

      Limit: 50 characters

    2. Description: (Optional) Enter information about the managed network.

      Limit: 255 characters

    3. Subnets: Click Add to specify the subnets, or group of hosts, to be managed.

      Enter each subnet using CIDR notation. For example, 0.0.0.0/0.

      NOTE: You can add a subnet to only one managed network. You will receive an error if you attempt to add the same subnet to another managed network. If you are unsure if an IP address has already been associated with a managed network, use the Resolve Network search box. For more information, see Resolving IP address.

    4. Passwords Managed By: Select the appliances to be used to manage the specified subnets.

      NOTE: You do not need to specify an appliance when you initially define a managed network. You can use the Edit button to specify the managing appliance at a later time.

    5. Sessions Managed By: If applicable, select the Safeguard for Privileged Sessions (SPS) appliance to associate with the managed network.
  4. Click OK to save your selections and add the managed network.

Deleting a managed network

To delete a managed network

  1. Go to Managed Networks:
    • web client: Navigate to Cluster | Managed Networks.
    • desktop client: Navigate to Administrative Tools | Settings | Cluster | Managed Networks.
  2. Select the managed network to be deleted, click Delete.
  3. In the confirmation dialog, click Yes.

Resolving IP address

As an Appliance Administrator, you can use the Managed Networks page to search for an IP address within a managed network's list of subnets.

To find an IP address in a managed network

  1. Go to Managed Networks:
    • web client: Navigate to Cluster | Managed Networks.
    • desktop client: Navigate to Administrative Tools | Settings | Cluster | Managed Networks.

  2. In the Resolve Network search box, type the IP address, and press Enter.

    The managed network that contains the subnet that most closely matches the IP address is highlighted. If there are no subnets that match the IP address, the Default Managed Network is highlighted.
